Wind loads on low-rise buildings-effects of roof geometry.

Describes measurement of wind pressures on low-rise buildings at Aylesbury. Pressures were recorded simultaneously at over one hundred positions divided between seven houses in an estate and a specially constructed building situated on open ground adjoining the state. The roof pitch of the experimental building could be quickly varied to any angle between 5 and 45 deg. and this was used to investigate the variation of pressure distributions over the surfaces of the building. Data are presented for two skew wind directions. Initial comparisons are made with wind-tunnel tests. Concludes that suction loads on roofs increase with decreasing roof pitch and recommends alteration in United Kingdom wind-loading code. NOTES See also abstract No. 307 for comparison with tunnel tests.
